COUPLING FOR PUMP-RODS.

Application filed May 10, 1916. Serial No. 96,611.

To all whom it may concern:

Be it known that I, CHRISTIAN ZEHR, a citizen of the United States, and a resident of Berne, in the county of Adams and State of Indiana, have invented new and useful Improvements in Couplings for Pump-Rods, of which the following is a specification.

My invention is an improvement in conplings for-pump rods, and the invention has for its object to provide mechanism for connection with a pump, comprising a bracket having uprights provided with upper and lower guides for the rod, and a pumping bar of substantially yoke shape and comprising a vertical body on the opposite side of the rod from the uprights, and arms having guide openings for receiving the rod and having means for permitting the bar to be connected with a windmill or a pump jack, the lower arm of the bar being extended between the uprights and adapted for connection with the pump handle, and said handle being arranged to form a rigid brace between the upper arm and the lower arm when in inoperative and lowered position.

In the drawings:

Figure 1 is a perspective View of the improved coupling,

Fig. 2 is a side view with parts in section,

Fig. 3 is a section on the line 33 of Fig. 1,

Fig. 4 is a side view showing the manner of connecting a pump jack and with parts in section,

Fig. 5 is a section on the line 55 of Fig. 1, and

Fig. 6 is a vertical section showing a modified construction.

In the embodiment of the invention shown in Figs. 1 to 3, a bracket 1 is provided having a threaded opening 3 which is adapted to be engaged by the threaded upper end 2 of the portion 4: of the pump, and this bracket is provided with a pair of laterally spaced substantially parallel uprights 5. These uprights 5 have integral guide lugs 6 and 7 at their lower and upper ends respectively, for the pump rod 8, and the sa d rod extends through the guides shown 1n Figs. 1 and 2. A pumping member or bar 9 is provided, the said bar having upper and lower laterally extending arms 10 and 11,'and these arms have openings through which the pump rod extends. The openings Specification of Letters Patent.

of the guide'lugs 6 and 7 and of the arms 10 and 11, are in alinement, and the pumping rod 8 is freely movable in the openings of the lugs and arms, when the said rod is op erated manually in a manner to be presently described. I

The pumping bar 9 is on the opposite side of the rod from the uprights 5, and the lower arm 11 of the said bar is extended between the uprights, and is provided with an opening for receiving a bolt 12 which pivotally connects the said extension with one end of a link 13. This link 13 has its ends forked as shown, and the arms of the fork at one end engage over the extension of the arm 11, and have openings registering with the opening of the extension for receiving the bolt 12. The arms of the fork at the other end of the link engage opposite sides of a laterally extending lug 14: on a pump handle 15, and a bolt 16 is passed through registering openings in the arms and the lugs to pivotally connect the handle to the link. The pump rod 8 has openings 17 spaced apart vertically from each other, for receiving a bolt 18, which pivotally connects the pump handle with the pump rod. The arrangement of the link 13 and of that portion of the pump handle between the lug 14 and the bolt 18 is such that when the parts are in the position of Fig. 2, that is when the pump handle is in inoperative downward position, the link and the said portion of the pump handle will be in alinement, forming thus a species of toggle joint, between the extension of the arm 11 and the bolt 18, and the aggregate length of the link and thefsaid portion of the pump handle is such that when the toggle joint is in .alinement, the upper end of the pump handle will be adj acent to the upper arm 10 of the pumping bar.

With the parts-in this position it will be evident that when the pumping bar is reciprocated, in a manner to be presently described, the pump rod will also be reciprocated, thetoggle joint forming a rigid strut for preventing movement of the rod with respect to the pumping bar. When the pump handle is moved in the direction indicated in dotted lines in Fig. 2, the toggle joint will be broken, and the pump rod will be released from the pumping bar 9. The bracket 1 is provided at the lower ends of the uprights 5 with perforated lugs 19, and by means of a bolt indicated at 20 the lower end of the link 13 may be pivotally connected to these lugs, and at the same time to the extension of the arm 11, or if desired the pumping bar may be removed and the link 13 may, be pivoted directly to the lugs 19, thus forming a substantial hand pumping head. 7

The upper end of the bar 9 is channeled as indicated at 20, to form a species of socket, and one end of the wind mill rod 21' is received in the said socket and is secured to the bar by means of bolts and nuts 22. hen the wind mill is connected to the pumping bar, the pump handle 15 is placed as shown in Fig. 2, and it will be evident that when so placed, the pump rod must move with the bar 9.

In Figs. 4 and 5 the pumping bar 9 is shown connected with a pumpjack indi-' cated at 21, by means of connecting links 25. These links 25 are pivoted at one end by means of a bolt 26 to a perforated lug 27 on the outer face of the bar, and the opposite ends of the links are connected to crank arms 28 on a shaft of the pump jack. The

. jack 2 1 is of ordinary construction and is arranged adjacent to the pump r, and it will be evident that when the jack operates, the pump rod will be reciprocated. WVith this arrangement, the bolt 18 which connects the pump handle to the rod is arranged in the uppermost opening 17, while when arranged as shown in Fig. 1, the bolt is in the lowermost opening. The distance between the arms 10 and 11 of the pumping bar is such with respect to the distance between the guides 6 and 7, that a six or eight inch stroke is permitted, and it will be obvious that these parts will be so spaced with relation to each other, that any desired stroke may be obtained.

When the bolt 20 is engaged with the lugs 19, as shown in Fig. 3, the pumping bar 9 is held from movement with respect to the bracket 1, While when the parts are in the position of Fig. 4, the pumping bar is released from the brackets. (In order to con- Y vert' the pump from a manually operated,

into a mechanically operated pump, it is only necessary to change a single bolt 20.) If. windmill only is used with this pump, the

. wooden wind mill rod 21 is bolted direct to socket 20 as shown in Fig. 2. But in cases where windmill, and pump jack both are used on the same jpump, we bolt to socket 20* the short fiat rod, as shown in Fig. 4. This rod'21 has a' hole near its upper end and makes connection with :any windmill rod with a pin andv cotter. This same pin makes the change between this and the pump jack, bolt or pin 26. In addition the pump handle may be operated at any time, whether the rod is in motionor not, for the first upward movement of the pump handle breaks the toggle joint and releases the handle from the moving pump red. It is never necessary to disconnect the pump from the windmill or from the jack, in order to permit the same to be operated by means of the handle 15, and the pump can be operated manually without requiring any release.

In Fig. 6 is shown a construction especially adapted for use as an economical oneway pump for tubular wells. Vith this construction the well pipe 30 has connected with the top thereof one of the ends of a T 31, and a nipple 32 is connected with the lateral branch of the T, serving as a delivery pipe. A short section 33 of pipe is threaded into the upper end of the T, and this section 33 has a cap 34 at its top, the cap having an opening through which extends the pump rod 35.

A pumping bar 36 which corresponds to the bar 9 of Figs. 1 to 5, is provided with upper and lower arms 37 and 38 respectively, having alined openings through which extends the pump rod 35, and the pumping bar is slidable on the rod. The bar has a socket 39 to which is connected the wooden windmill rod 21 shown in Fig. 2. The lower arm 38 of the pumping bar is extended on the opposite side of the pump rod, and the pump handle 42 corresponding in form to 95 the pump handle 15, is pivotally connected by a. link 43 with the extended arm 38, the arrangement of the link and the pump handle being such that they constitute a toggle joint in the same manner as the handle 15 100 and the link 13.

With this arrangement, when the pump handle is in lowered position, that is with the toggle in alinement, it will be evident that. when the windmill operates the pump- 105 ing bar 36, the pump rod will be moved therewith, while when the toggle joint is broken, the pump rod may be operated by the handle without the necessity of diseonnecting the pump. In Figs. 4 and 5, when 110 the windmill is connected to the pumping bar, the rod 21 of the mill is connected directly to the socket, as shown.
